Tickets assigned to Team email to old list

Just noticed this today. Create a new Ticket and assign it to a Team. Notification email is sent to a list of email addresses that's years out-of-date; doesn't have current Team members and includes Retired users. I've checked Team memberships in the Administrator and it looks good. Auto-Assignment was not on, but I activated it and no change in behavior. What am I missing?

Re: Tickets assigned to Team email to old list

Further investigation indicates that current Team members are in the email list, but it is pulling Retired users as well. As a workaround, we temporarily reactivated the Retired users, unchecked their ability to be "Notified of New Tickets" and "Available for Calls", then Retired them again.
